This is a cost-effective and efficient solution for metal detectorists seeking a lossless, low-latency (APTX) Bluetooth wireless headphone setup. Compatible with any metal detector featuring a 3.5mm audio jack, this system ensures seamless audio transmission with minimal delay. In my testing, I used it with a Minelab Xterra Pro and confirmed its reliability across multiple detectors, including the Rutus Alter 71, Deeptech Vista Gold Gain, Minelab Equinox 700, and Minelab Vanquish 340. Regardless of the detector, performance remained consistent, delivering real-time, uninterrupted audio feedback.

The Issue: Bluetooth Latency in Metal Detecting
Standard Bluetooth transmitters (£7-£15) paired with regular Bluetooth headphones often introduce a significant audio delay, making them unsuitable for metal detecting. This latency results in an audible signal lag, meaning you hear the detection tone when the coil is 30-40cm past the actual target—a critical drawback for precision detecting.
I initially tested this setup using high-quality Sony headphones, but the delay rendered them impractical for real-world use. Accurate target pinpointing requires real-time audio feedback, making low-latency (APTX) solutions essential for serious detectorists.
The Solution: APTX Low-Latency Headphones & Bluetooth Transmitter
To overcome the issue of audio lag, a low-latency (APTX) Bluetooth setup is essential. This ensures near-instantaneous audio transmission, allowing you to hear signals in real-time without any delay that could affect target pinpointing. After extensive testing, I found an effective and affordable solution using components readily available on Amazon:
- Sound Blaster JAM V2 Bluetooth 5.0 Wireless Headphones – Featuring APTX Low Latency, these headphones provide clear, uninterrupted audio with minimal delay.
- 1Mii Bluetooth 5.3 Transmitter (3.5mm Jack Plug) – A high-quality transmitter designed for seamless connectivity with any metal detector equipped with a standard 3.5mm audio jack.
This combination ensures a lossless, low-latency audio experience, making it ideal for metal detecting. Click the images below to check current prices and availability on Amazon.

Setup & Testing: Achieving Low-Latency Wireless Audio for Metal Detecting
Setting up this low-latency Bluetooth system is quick and straightforward. Follow these steps to ensure optimal performance:
1. Charging the Devices
Before use, fully charge both the transmitter and headphones using the supplied USB leads and plug. A full charge ensures uninterrupted performance during detecting sessions.
2. Pairing the Headphones with the Transmitter
- Headphones: Press and hold the power button on the Creative Labs Sound Blaster JAM V2 headphones (located on the right side, large disc).
- Transmitter: Set the 1Mii Bluetooth 5.3 Transmitter to TX mode by sliding the switch, then press and hold the circular button until pairing initiates.
- Within seconds, the headphones should confirm the connection with an audio prompt such as “Paired.”
3. Connecting to Your Metal Detector
Once paired, simply plug the transmitter into your detector’s 3.5mm headphone jack. Start detecting as usual—swing the coil over a target and listen for instant audio feedback.
Performance & Real-World Testing
Through multiple live detecting sessions, I found this setup to work flawlessly. The latency is negligible (estimated at <50ms)—I couldn’t detect any perceptible delay. Target signals were accurate, and pinpointing was effortless.
Potential Interference: Low Background Buzz
One minor issue I encountered was a faint background buzz, particularly noticeable in quiet environments. However, this was easily mitigated by adjusting the threshold volume on my Minelab Xterra Pro to around 10. Over time, this sound becomes imperceptible as your brain naturally filters it out.
Final Verdict
This lossless Bluetooth setup has proven to be an effective and practical alternative to expensive proprietary wireless solutions. For metal detectorists seeking a budget-friendly, low-latency audio system, this configuration delivers excellent results in real-world conditions.
